SHUTTLE-BOX MOTION FOR LOOMS.

Specification of Letters Patent.

Patented Oct. 10, 1905.

To (1N 21/71/0171, it may concern:

Be it known thatI, HENRY BARDSLEY, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Shuttle-Box Motions for Looms, of which the following is a specification.

My invention relates to shuttle-box motion for looms, and particularly to that class of shuttle-box motions shown and described in my Letters Patents Nos. 626,960 and 681,648.

The object of my invention is to improve upon the construction of some of the parts of the shuttle-box motion shown and described in said patents, and more particularly the master-gear, the mutilated pinions meshing therewith, the diametrical levers connected with said pinions, and the adjusting means for the cranks which operate the shuttle'box levers.

In my improvements I provide a plate combined with each set of teeth on the mastergear, extending along one side or edge of the teeth, with a recess therein at each end. I provide each mutilated pinion with four teeth longer than the other teeth and a diametrical lever for each mutilated pinion which does not have a pivotal motion, as shown and described in said patents, but has a sliding or longitudinal motion with means for operating it. I also provide a single adjustingscrew for the crank-plate of the mutilated pinion, all as will be hereinafter fully described.

I have only shown in the drawings sufficient portions of a six-shuttle-box motion for looms of the type shown and described in said pat ents, with my improvements combined therewith, to enable those skilled in the art to which my invention belongs to understand the construction and operation of my improvements.

Referring to the drawings, Figurel is a side elevation of a portion of a loom frame or side and parts of a six-shuttle-box motion with my improvements combined therewith looking in the direction of arrow (0, Fig. 2. Fig. 2 is a plan view of the parts shown in Fig. 1 looking in the direction of arrow 6, same figure. Fig. 3 is a side view of one of the mutilated pinions, the diametrical lever connected therewith, and the operating-lever looking in the direction of arrow 0, Fig. 4. Fig. A is a top or plan view of the parts shown in Fig. 3 looking in the direction of arrow (Z. Fig. 5 is an end view of the parts shown in Fig. 4 looking in the direction of arrow 0, same figure. Fig. 6 is a vertical section on line 6 6, Figs. 4 and 5, looking in the direction of arrow 0, same figure. Fig. 7 is an end view of the adjustable crank-plate and crank-pin for operating the box-levers looking in the direction of arrow f, Fig. 8. Fig. 8 is a side view of the parts shown in Fig. 7 looking in the direction of arrow 0, same figure. Fig. 9 is a side view of the parts shown in Fig. 8 looking in the direction of arrow It, same figure; and Fig. 10 is a vertical section on line 10 10, Figs. 7 and 9, looking in the direction of arrow i, same figure.

In the accompanying drawings, 1 is a part of a loom side or frame.

2 is a stand or support for the several parts of the shuttle-box motion secured to the loom side 1 by bolts 2 or otherwise.

3 is the bottom or cam shaft of the loom.

4 is a mutilatvd driving-gearsecured to the shaft 3 and adapted to mesh with and communicate an intermittent motion to a gear 5, fast on the hub of the master-gear 6, mounted on a stud 2. The master-gear 6 has in this instance four sets of teeth 6 on its periphery and also has extending along on one side or edge of said teeth a plate 6", the outer edge of which extends a little beyond the outer ends of the teeth 6. The plate 6 is preferably made integral with the rim of the master-gear 6; but it may bemade separate therefrom and attached thereto. if preferred. At each end of the plate 6 there is a recess 6' a little deeper than the recesses between the teeth 6. (See Fig. 1.) The master-gear 6 is adapted to mesh with and operate in this instance three mutilated pinions7. Each mutilated pinion T has in this instance two sets of teeth 7 thereon, with a plain space between the same. The end teeth 7" of each set of teeth 7' are slightly longer than the other teeth (see Fig. and adapted to enter the recesses 6 in the plates 6 0n the master-gear6. The recesses 6"are the full width of the master-gear and the plate. The teeth 7 are of a corresponding width, Figs. 2 and 3. Each pinion 7 is fast on its supporting-shaft 8, which may be tubular, as shown, and is mounted to rotate in suitable bearings,

'IOO

and on the front face of each pinion 7 is a groove or way for a diametrical lever or bolt 9. The diametrical levers or bolts 9, which may be generally denominated starting tooth-carriers, do not have aspivotal motion,

as shown and described in said Patents Nos. 626,960, and 681,648, but have a sliding or longitudinal motion to be moved into and out of engagement with the ends of the plates 6" on the master-gear 6, according to the indications of the boxpattern chain. Each diametrical lever or bolt 9 has on its external surface two projections or stops 9, which are adapted to engage a block 10, in this instance held by a pin 10 between the two projections 11 on the front face of each mutilated pinion 7. The engagement of the projections 9 with the block 10 limits the sliding motion of the diametrical levers or bolts 9. Each diametrical lever or bolt 9 has a slot or opening 9" therein, into which extends the end of one arm of an angle-lever 12. The angle-lever 12 is pivotally mounted on a transverse pin 13, supported in the outer ends of the two projections 11 on the mutilated pinion 7. A spiral spring 14 encircles the hub of the angle-lever 12 and is fast at one end to one of the projections 11 and engages with its other end the angle-lever 12 and acts to move said angle-lever 12 and through said lever to move the diametrical lever or bolt9 into its inoperative position out of engagement with the master-gear 6. The other arm 12 of the anglelever 12 extends in the path of an indicatingfinger 15. One of the two indicating-fingers 15 for one of the upper mutilated pinions 7 is fast on a rock-shaft 16, mounted in suitable bearings (see Fig. 1) and is operated through an arm 17, also fast on said shaft 16 and connections to the box-pattern chain (not shown) in the usual and well-known way. The other indicating-finger 15 is loosely mounted on the shaft 16 and is operated by an arm 18 and connections to the box-pattern chain. (Not shown.) The indicatingfinger 15 for the lower mutilated pinion 7 (shown in Fig. 1) is loosely mountedon a transverse rod or shaft 19 and has an arm 20 thereon and connections therefrom to the box-pattern chain. (not shown,) all in the usual way and as shown and described in said Patents Nos. 626,960, and 681,648.

It will be understood that according to the indications of the box-pattern chain (not shown) each of the fingers 15 for each of the three mutilated pinions 7 are operated to positively move the diametrical lever or bolt 9 into engagement with the master-gear 6 against the action of the spiral spring 14. The spiral spring 14 acts to move back the diametrical levers out of engagement with the master-gear 6 when the fingers 15 are released, as shown at the left in Fig. 2.

21 is a cap which is secured to the stand 2 and extends around a portion of a mutilated pinion 7, as shown in Figs. 3, 4, and 5. The cap 21 has a slot 21 therein to receive the end of the diametrical lever or bolt 9 when it is moved out of engagement with the mastergear 6, and thus lock and prevent any further forward rotation or any backward movement of the mutilated pinion.

On the inner end of the shaft 8 of each mutilated pinion 7 is a disk or plate 22, which may be madeintegral with said shaft, as shown in Fig. 10. Said disk 22 has two parallel projections or ways 22 thereon. (See Figs. 7 and 9.)

23 is'a crank-plate extending between the two projections 22 and having thereon acrankpin 24. The plate 23 has slots 23 therein and is adjustably secured to the outer face of the disk or plate 22 by two bolts 25. (See Fig. 7.)

The crank-pin 24 on each crank 23 for each mutilated pinion 7 is connected through a connector 24 to the compound box-levers 26 and 27, (shown in Fig. 1,) and the compound box-levers 26 and 27 are connected to the giveway connector 28, which is connected with the boxrod 29, all in the usual and well-known way.

In order to adjust the position of the crankplate 23 and the crank-pin 24 thereon to vary the movement of the box-levers, I use a single adjusting-screw 30, (see Fig. 10,) the outer end of which has an annular groove 30 therein to extend into a slot 22 in the disk 22 and the inner screw-threaded end of which passes through a screw-threaded opening in an inwardly-extending lug 23 on the crank-plate 23. It will be seen that by means of the single adjusting-screw 30 the position of the crankplate 23 and the crank-pin 24 thereon may be adjusted as desired by turning said screw 30.

It will be understood that the operation of the several parts of the shuttle-box motion shown in the drawings to operate the shuttleboxes is the same as the operation of the shuttle-box motion shown and described in said Patents Nos. 626,960 and 681,648.

The advantages of my improvements will be readily understood by those skilled in the art. In the ordinary'construction of the mastergear, without the plate on one side of the teeth, the teeth on the mutilated pinions are liable to come into mesh with the teeth on the master-gear at the wrong time and in the wrong place through the pivoted diametrical lever sticking or the actuating-spring therefor becoming weakened or not being properly adjusted. This will cause a breakage of some kind. By means of the plate extending along one side of the teeth, having the two openings 6 at each end thereof for the longer teeth 7 on the mutilated pinions 7, the mutilated pinions are not so liable to come into mesh at the wrong time or in the wrong place, and therefore the chances of breakage are done away with.

The longitudinal movement of the diamet- IIO rical lever or bolt 9 of each mutilated pinion is more accurate and positive than the pivotal motion of the diametrical lever shown and described in the Patents Nos. 626,960 and 681.6%, referred to, and it is cheaper to make, and in case of breakage of the actuatingspring 14: of the angle-lever 12 said spring can be readily replaced, which is not the case with the equivalent springs 19 and 10, respectively, of said patents. The employment of one adjusting-screw, as 30, and two screws to secure the crank-plate in place is simpler and cheaper than the construction shown and described in said patents.

I have only shown in the drawings my improvements combined with a six-shuttle-box motion; but it will be understood that my improvements may be used with a two or four shuttle-box motion of the class referred to on one or both sides of the loom. 7

It will be understood that the details of construction of my improvements may be varied, if desired.
